Emotion Remote Control: I Broke the Princess!

After being reborn into a Japanese-style Western fantasy galgame world, Karl discovered that he had become an exceptionally rare turncoat. The arrogant Seven Kingdoms Alliance not only suppressed the Holy Father Church, but also sought to wipe out every non-human race. As a fallen holy son of the church, he couldn't bear to be bullied day after day by the princesses, so he secretly made contact with the protagonist among the demons, providing him with plenty of intelligence and assistance. The protagonist promised that once the Seven Kingdoms fell, Karl could do whatever he wanted with the princesses. But Karl, whose memories of his previous life had returned, knew this was just an empty promise! No matter which storyline he followed, the protagonist would use him and then toss him aside. He was nothing but a tool, destined for a gruesome death. Even worse, the protagonist's golden finger was something Karl himself had given him... Hm? Wait a second. Looking at the extraordinary magic stone in his hand, which could control other people's emotions, Karl suddenly realized: he hadn't given it away yet... Then there's no problem.
